Tokyo Shinjuku's Okada emergency line is a golden line, along which there are many natural or cultural attractions, of which Okada Harakawa is one of the most well-known. It was autumn when we went, and we met a lot of old people on foot. They were well equipped and often walked for exercise. There were many news organizations and volunteers in the park. It turned out that these two days were the 30 kilometer cross-country race for the old people on foot. It was a beautiful sunset. On the way, we met many ancient warriors dressed up as well as other ancient dresses of men, women, old and young. As time goes back, we are back to the shogunate era. The original town of Oda is not very large, and the Tianshouge Pavilion was rebuilt after being destroyed, but the old is as old as before, and the old style stays, which is very Japanese. Boarding Tianshouge Pavilion and looking around, the sky is high and the earth is wide, the mountains and seas are quiet, countless houses shine like small boxes in the green fields, lighting up the sight and memory, making people unforgettable for a long time.
